Open Transaction Batches Posting to General Ledger 11i

Hello,

The General Ledger Transfer Program has posted some transactions from an open transactions batch, so they can no longer be amended.  From my research it seems as though there is no way to amend the setup to prevent this.  The options we have so far are:

1) Have a business rule that there are no open batches at the end of the day (transfer is run overnight).  But the problem can still happen by accident.

2) Only complete all the invoices after you have entered them all and checked the batch totals. There is the danger that we have more incomplete invoices in the system.
